This is one of the legendary Russian lenses. Made on the base of Flektogon but tweaked by the Russians this lens and other Russian lenses issued in 1958 were awarded in Brussels Show with the prestigious "Grand Prix" award. On the other side Mir-1B has very controversial state among photographers. One awe it, others hate it. The lens by itself is very well build. All metal finish, quality paint and robust construction. Image quality is great. The lens produces very snappy colors with great contrast. Wide open its sharpness is acceptable on but 5.6 and onward Mir becomes tack sharp. Bokeh is a little harsh in the highlights but it is a least of concern. Chromatic aberrations are very low to none but the lens easy catches flares so hood usage is recommended. As Flektogon derivate there is no distortion. The lens is ideal for shooting architecture. Mir is a great performer as a macro lens with extension tubes. To keep front protruded lens element clear from scratches and dust it is best to use UV filter. Mir-1b is small almost pocket size. This lens is one small Russian jewel that has an irreplaceable place in my photo bag.
